DIGITAL I/O
J9, J12 - Digital I/O
The EBC-C384 has 48 open collector digital I/O bits with a default base address of 120H. Each bit is configured as
an open collector with a 10K pullup. Each bit is able to sink up to 8mA. The first 24 lines are capable of fully latched
event sensing with polarity being software programmable.
Digital I/O Connectors
These 48 lines of digital I/O are terminated through two 50-pin connectors at
J9
and
J12
. The
J9
connector handles
I/O ports 0 through 2 while
J12
handles ports 3 through 5.
The I/O connectors can p5V to an I/O rack for miscellaneous purposes by jumpering
JP5
and
JP8
. When
JP5
is jumpered (1-2), +5V is provided at pin 49 of
J9.
When
JP8
is jumpered (1-2), then +5V is provided at pin 49 of
J12
.
It is the user’s responsibility to limit current to a safe value (less than 400 mA) to avoid damaging the CPU board.
